Title: Heat exchange apparatus
Inventor: CAVE-BROWNE-CAVE THOMAS REGINA
IPC: F28D7/04
Filed: 1957-11-06
Abstract: 846,592. Tubular heat exchangers. MA RSTON EXCELSIOR Ltd. Sept. 12, 1958 [Nov. 6, 1957], No. 34580/57. Class 64(3) A heat exchanger comprises a pluralty of externally finned tubes each formed as a multi-coil flat spiral in which the spirals are double wound (see Fig. 2) so that the tube ends may be connected to steam inlet and condensate outlet manifolds 15, 17 disposed adjacent the wall of a casing 1 containing the tube assembly, the spiral tubes being spaced apart e.g. by baffles 13, and a fluid such as oil to .be heated flowing over the tubes in a direction at right angles to the spirals. The tube fins preferably extend at right angles to the tube axes so as to lie parallel to the vertical axis of the casing. Steam is passed through the tubes to heat the oil. An additional spiral, located near the lower end of the casing and connected to the manifold 17, may provide an extended outflow path for the steam condensate. Oil enters the casing 1 through an inlet 19 and the discharge temperature of the oil may be controlled by a thermostat in the oil outlet pipe 21. The thermostat may regulate the admission of steam to, or the discharge of condensate from the tube assembly. The apparatus may be cleaned by opening a drain outlet 23 and admitting steam to the casing through a pipe 25.

Title: Improvements in the manufacture of artificial products from viscose
IPC: D01F2/12
Filed: 1933-12-08
Abstract: Artificial products such as artificial silk, horse hair, ribbons, capsules, or sheets are prepared from viscose by spinning or coagulating these products in an acid salt solution, the viscose containing one or more separately prepared xanthates of aromatic, hydroaromatic, cyclic or heterocyclic alcohols. Suitable alcohols are borneol, menthol, fenchyl alcohol, furfuryl alcohol, naphthene alcohol, decahydronaphthol, methylcyclohexanol, hexahydroisothymol, phenyl ethyl alcohol or phenyl propyl alcohol.  In an example, to viscose containing 7\ba1/2\be--8 per cent of cellulose, and 6\ba1/2\be--7 per cent of alkali, and having a common salt number of 7\ba1/2\be--8 is added 0,2 per cent of the sodium xanthate of phenyl ethyl alcohol, and the solution is spun into a bath containing 29 per cent of Na2SO4, 13 per cent of H2SO1 and a small amount of ZnSO4 according to the spinning conditions.  In another example, 0,25 per cent of fenchyl xanthate is added to a viscose, having a high degree of viscosity prepared from unripened alkali cellulose, and containing 6--6\ba1/2\be per cent of cellulose and 6\ba1/2\be per cent of alkali, and the solution is spun into a bath containing 27 per cent Na2SO4, 3 per cent of ZnSO4, and 11 per cent of H2SO4.  A third example describes the preparation of silk from viscose to which borneol xanthate has been added, and a fourth example describes the preparation of sheets from a viscose containing borneol xanthate. Products obtained by the process of this invention are said to be glossy and clear.  Specification 365,982 is referred to.

Abstract: 416,347. Speed governors. HESSELMAN MOTOR CORPORATION, Ltd., 56, Kingsway, London. Dec. 12, 1932, No. 35170. Convention date, Dec. 12, 1931. [Class 57.] A fuel-injection pump for an internal-combustion engine for a motor vehicle is controlled by a piston which is subjected to the pressure of the intake manifold. The piston 2, Fig. 2, sliding on a rod 5 in a cylinder 3, is exposed on one face to the pressure in the intake manifold through a pipe 29, the other face of the piston being open to the atmosphere. The piston is also acted on by a weak spring 9 and a strong spring 13, which come into action successively. The piston carries a cam 8 engaging a screw 18 in one arm 16a of a bell-crank lever, secured on a spindle 15, which carries stops 22 for limiting the stroke of the fuel-pump plunger 23. The maximum amount of fuel which can be injected is limited by means of a screw 27, which engages the arm 16b of the bell-crank lever, and the device can be put out of action by means of a sliding rod also engaging the arm 16b. The minimum amount of injection is adjusted by means of the screw 18, which can be rotated by hand, or by a governor, or by a device operated by the atmospheric pressure. The cam 8 may have varying contours, which can be brought into action by rotating the cam. Specification 282,731, [Class 7 (iii)], is referred to. The Specification as open to inspection under Sect. 91 describes also a modification in which the piston 2 is secured to its rod, and the rod engages a forked lever on the governing spindle 15. Also a further modification, Fig. 5 (Cancelled), in which the rod of the piston 2 engages a rod or rack 41, by means of which the pump plunger can be rotated, or a nut can be rotated for limiting the plunger stroke. The setting is adjustable by means of a rod 47, movable in the interior of the rod by means of a screw 18. This subject-matter does not appear in the Specification as accepted.

Title: Process for brightening organic materials and temporary support therefore
IPC: D06L3/12
Filed: 1968-07-24
Abstract: 1.243,219. Brightening organic materials. SOC. D'EXPLOITATION DES PROCEDES SUBLISTATIC. 24 July, 1968 [24 July, 1967], No. 35311/68. Headings D1B and D1P. [Also in Division B2] An organic material, e.g. a fabric or foil is optically brightened by printing a temporary support in the form of a sheet, strip or ribbon with a solution, emulsion or dispersion of an optical brightening agent which is heatstable up to 250C and vapourises at 150- 220C at atmospheric pressure and a binder or thickener which is heat-stable up to at least 250C and non-sublimable at the sublimation temperature of the brightener, drying the print, bringing the printed surface into contact with the organic material to be brightened and heating to above 150C for the time required to allow vapourisation and penetration of the optical brightening agent into the material to be brightened. The temporary support may be a sheet of nonporous or slightly porous paper, a sheet of aluminium the unprinted face of which may be glued onto a strip of strengthening paper, or a film of regenerated cellulose. The brightening agent may be a benzoxazole thiophene, a dibenzothiophene-S-dioxide which may contain amino group which may be acetylated, a coumarin, a pyrazoline, a mono-oxazole or bis-oxazole, numerous examples of which are given. Suitable thickeners are sodium alginate, carob or gum tragacanth, carboxymethyl cellulose, nitrocellulose or methyl, ethyl, hydroxyethyl or hydroxypropyl cellulose. The compositions used to apply the optical brightening agent and thickener or binder to the temporary support is preferably free from water and may contain methyl ethyl ketone and ethyl or isopropyl alcohol and may be applied by printing to the entire surface or locally. A dyestuff, e.g. 1-hydroxy-3-phenoxy-4-aminoanthraquinone, 1, 4-dimethylaminoanthraquinone, 4- (4'- methyl-2'-nitrophenylazo)-3-methyl-5-pyrazolone, the butyl or propyl ester or 1, 4-diaminoanthraquinone-2-carboxylic acid or 3- hydroxyquinophthalone, vapourisable in the same temperature range as the optical brightening agent may also be applied to the temporary support so that coloured patterns are produced. Heating of the temporary support in contact with the material to be brightened may be effected by means of an iron or pressing machine, heated plates or heated cylinders. Woven or knitted fabrics, veils, lawns, felts or carpets comprising cellulose acetate, polyacrylonitrile, polyethylene terephthalate, nylon, cotton or wool fibres may be brightened.
